Crash Intelligence That Works the Way You Work
StreetExplor turns years of crash records into a free, public map your analysts, planners, and officers can use today — no software purchase, no training required.
What it is
A street-level crash map built for public safety professionals
Most agencies already have crash data somewhere — in a state DOT database, in a records management system, in annual reports that take weeks to compile. The problem is that raw data doesn't answer the question a traffic commander or city engineer actually needs to answer on a Monday morning: which specific streets are the problem, and what's driving the crashes there?
StreetExplor answers that question directly. We take publicly available crash records, join them to the road network at the individual street-segment level, and put the result on a color-coded map that anyone can use without GIS training. Every segment carries five years of crash history, filterable by 30-plus variables — weather, time of day, crash severity, driver age, road surface, light condition, and more.
Click any segment and you see its full trend line. Filter by Fatal/Serious Injury and the dangerous corridors stand out immediately. Change the year and see whether things are getting better or worse. The whole thing runs in a browser, free, with no account required.
Program alignment
Built for the programs your agency already runs
Every major federal and state traffic safety program requires the same foundation: documented evidence of where crashes occur and why. StreetExplor provides that evidence at the street-segment level — the granularity reviewers expect but that statewide statistics can't deliver.
Highway Safety Improvement Program
FHWA / State DOTHSIP demands a data-driven, performance-based approach and documented crash concentration evidence for every funded project. StreetExplor satisfies the project identification requirement, supports before-and-after evaluation, and provides non-motorized safety data for the federally required set-aside — all without analyst time or GIS work.
NHTSA Section 402 & 405 Grants
State Highway Safety OfficesEvery 402 application must document a specific, data-identified problem before proposing a solution. Section 405 national priorities — impaired driving, motorcyclist safety, occupant protection, teen drivers — each map directly to StreetExplor filter combinations that pull exact corridor-level evidence in under ten minutes.
Safe Streets and Roads for All (SS4A)
USDOT — $5B Program, Cities & Counties EligibleSS4A funds cities, counties, and MPOs to develop Comprehensive Safety Action Plans and implement projects. The Action Plan — required before any Implementation Grant — must identify the most significant crash concerns for all road users. StreetExplor provides that crash evidence base and supports the equity analysis, multi-user documentation, and post-project impact measurement SS4A reviewers look for.
Strategic Highway Safety Plan
State DOT / Multi-AgencySHSPs organize safety work around emphasis areas — roadway departure, intersection safety, young drivers, impaired driving, non-motorized users. StreetExplor's 30-plus filters map onto each area, providing the street-segment evidence that FHWA reviewers expect but that aggregate statistics cannot deliver. Updated every five years, an SHSP's data chapter is one of the most time-consuming sections to write. StreetExplor cuts that time significantly.
Vision Zero & Zero Fatalities Programs
Cities, Counties & State DOTsVision Zero requires identifying the precise locations where fatal and serious crashes concentrate, engaging communities with understandable data, and tracking progress against a long-term goal. StreetExplor's Fatal/Serious Injury filter does the first job immediately; its publicly accessible browser format makes it usable in community meetings; and its year-by-year per-segment trend data creates the baseline every Vision Zero program needs to measure whether it's working.
National Roadway Safety Strategy — Safe System Approach
USDOT Framework, embedded in HSIP, SS4A, and all federal safety programsThe Safe System Approach — now the governing framework for federal safety investment — addresses five pillars: safe roads, safe speeds, safe vehicles, safe people, and post-crash care. StreetExplor provides infrastructure evidence (unlit segments, wet-road concentration), speed management data (high-severity corridors), behavior targeting (young driver and late-night hotspots), non-motorized safety documentation, and geographic clustering of severe crashes to inform EMS pre-positioning. All five pillars, one tool.
In practice
What analysts actually do with it
These aren't theoretical applications — they're the specific tasks that traffic safety analysts, city engineers, and enforcement commanders run when they open the map.
Spot where crashes are getting worse
Switch between years while keeping the same filter active. Segments that jumped from yellow to orange — moderate to elevated risk — stand out immediately. No database export, no pivot table.
Measure whether a previous intervention worked
Click any treated segment and read five years of crash counts in the popup. A location dropping from 14 crashes to 5 after a signal installation gives you the before-and-after documentation HSIP closeout reports require.
Seasonal campaign targeting
Selecting a weather filter alongside a month shows exactly which corridors carry the highest risk under that combination. Safety campaigns can target those streets directly instead of running generically statewide.
Pre-position resources before bad weather
Before a forecast storm, the historical pattern shows which specific highway segments have the worst record under those conditions. Maintenance crews and patrol can be pre-positioned on confirmed high-risk corridors rather than dispatched reactively.
Deploy enforcement where and when it matters
Combining light condition, day type, and time filters identifies the corridors where high-risk conditions converge. Officers placed at those locations at those times are working where the data says harm concentrates.
Document program justifications with specific data
A grant application or safety plan that names specific corridors with documented crash rates is more credible — and scores higher in federal review — than one citing statewide statistics. StreetExplor pulls that corridor-level evidence in minutes.
Give public campaigns a local hook
A safety campaign that names a specific intersection resonates more than a generic reminder. Filtering by Fatal/Serious Injury surfaces the exact locations that should anchor public education messaging.
Understand what's actually driving crashes at a given location
A corridor shows high total crashes but no one knows why. Work through filters one at a time: wet-road crashes are elevated, dark-unlighted crashes are very high, afternoon-rush crashes are elevated. That combination tells a specific story — lighting, drainage, and geometry — so the engineering recommendation is defensible rather than generic.

An AI-assisted patrol optimization system that builds routes based on historical risk patterns, time of day, and available units — putting officers where the data says they're needed most.
PremiumThe bigger picture
Data that connects agencies and communities
The most persistent safety problems don't get solved by enforcement alone. They get solved when agencies and communities agree on what the problem is, where it is, and what to try. Shared data is how that conversation starts.
Shared situational awareness
When a city council member, a traffic engineer, and a patrol sergeant all look at the same map, the conversation shifts from opinions to evidence. StreetExplor gives every stakeholder the same view of the problem.
Community trust through transparency
Showing residents exactly where crashes occur — and what conditions are involved — builds public confidence in safety decisions. It turns "we know there's a problem here" from a complaint into a documented fact.
Evidence for engineering change
Years of crash data at a single intersection give engineers the evidence to prioritize a redesign, justify the cost, and later document that the change worked. That cycle is the foundation of a safe system approach.
